PROCESS OF SEPARATING HAIR FROM HAIRCLOTH.

No Drawing.

To all whom it may concern Be it known that I, MORRIS BRonKowsKY, acitizen of the United States, residing at Milwaukee, in the county ofMilwaukee and State of WVisconsin, have invented new and usefulImprovements in Processes of Separating Hair from Haircloth, of whichthe following is a specification.

This invention relates to a process of -sep-- cloth is first submergedin a solution con-- sisting of nine parts of water and one part ofcarbolic acid. After the cloth has been subjected to the action of thissolution for a period of about one-half hour it is removed, wrung outuntil freed as far as possible from the solution and then put in anordinary hot drier and retained therein until thoroughly dried. It isthen removed and tumbled or tossed about in a revolving receptaclewhereby the cloth will beagitated, such a itation causing the hair toseparate from the body of the cloth. The hair thus treated and recoveredwill be unaffected by the solution, except in a desirable way by theincidental cleansing action of the solution,'and will retain all of itspristine value for commercial use.

It will be understood that the action of the solution places thevegetable fibers of the cloth in condition to be partially carbonized orrendered brittle under the action of the drying heat, so that in theagitating action such fibers will break or separate by' may berecoveredfrom waste or refuse cloth in a quick and economical manner and renderedavailableforfurther use, without impairing thestrength or elasticity ofthe hair .or any I of the deleteriousv results and ex- Specification ofLetters Patent. Application filed December 17, 1910. Serial No. 597,840.

penses arising from the use of the acid solutions commonly employed.

Having thus described the invention, I claim 1. The herein-describedprocess of separating hair from hair-cloth, which consists in subjectingthe cloth to the action of dilute ca rbolic acid, drying the cloth bythe action of heat until the vegetable fibers are weakened and renderedbrittle, and then disintegrating the vegetable fibers to free the hairtherefrom.

2. The herein-described process of sepzirating hair from hair-cloth,which consists in subjecting the cloth to a dilute solution of carbolicacid, drying the cloth by the action of heat, and then agitating thecloth,

until the hair separates therefrom.

3. The herein-described process of separating hair from hair-cloth,which consists in submerging the cloth in a solution of carbolic acidand water, removing the cloth and displacing more or less of thesolution therefrom, drying the cloth by the action of heat, and thentumbling and agitating the cloth until the hair separates therefrom.

4. The herein-described process of separating hair from hair-cloth,which consists in subjecting the cloth to the acti an of a solution ofphenol, drying the cloth by the action of heat until the vegetablefibers are weakened and rendered brittle, and then disintegrating thevegetabie fibers to free the hair therefrom.

5. The herein-described process of separating hair from hair-cloth whichconsists in subjecting the cloth to the action of a solution of phenol,drying the cloth by the action of heat until the vegetable fibers areweakened and rendered brittle, and then agitating the cloth until thehair separates therefrom.

In testimony whereof I affix my signature in presence of two witnesses.5
